CASH-CARREEFL SPECIFICATION forming part of Letters Patent No. 341,825,dated May 11, 1886.

(No model.)

To all whom it may concern.-

Be it known that I, SAMUEL W. BARR, a citizen of the United States,residing at Manseld, in the county of Richland and State of Ohio, haveinvented certain new and useful Improvements in Cash-Carriers; and I dodeclare the following to be a full, clear, and exact description oi' theinvention, such as will enable others skilled in the art to which itappcrtains to make and use the same, reference being had to theaccompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specification.

Figure 1 of the drawings is a representation of a side elevation, partlyin section. Fig. 2 is a longitudinal central section; and Figs. 3 and iare detail views of the cash-car.

This invention has relation to vacuum cashcarriers; and it consists inthe construction and novel combination ot' parts, as will be hereinafterset forth, and pointed out in the claims.

Referring by letter to the accompanying drawings, A designates thetrackwire, which is stretched between the stations.

Bis a casting, which is secured to any suitable support, and the trackwire A runs through said casting and connects the station with thecashiers desk.

D is ahorizontal tube or pipe, which is connected to the casting B by athreaded connection.

E is an air-tight valve-head, which is composed of, the piston-head o,packing b, and washer c, held together by thepitinenor plungers s s.

In Fig. 2, B2 is a valve-head similar to the valve-head E, and to thisvalve head B2 a cord, T, is attached and runs over a pulley, G,

4o journaled in a recess, H, in the under side of the casting B. At itslower end the cord Tis provided with a handle, T.

At the end of the pitnian rods s s, which project through openings inthe casting B, is provided a pitman-head, I, which strikes the cash-car,which latter is held on the trackwire A in front of the casting by thespringarms J J, projecting horizontally from the front end of eachcasting. These springs also receive the car when returned to thestation, and serve to prevent a rebound of the car when it strikes thestation.

L designates a coil or spiral spring, which encircles the plunger rods,and returns the plunger to place after it has been projected. A weighteddog, G', is pivoted to the sides of the casting B and engages theplunger-head F, and'holds the latter in readiness to be projected. Whenthe draw rope T is pulled down quickly,the spiral spring contractswithin the pipe or tube, and the valve-head B2 moves forward in thetube, creating behind it what is termed a vacuum77 in the tube. When theknot or swell Z on the draw-rope T, reaches the loop Z, the dog G isreleased, and the valve-head E moves forward in the tube to fill thevacuum, and thus projects the plunger and drives the cash-car along the4track to the cashiers desk. As soon as the draw-rope has been releasedthe spring L eX- pands and returns the pitinan-heads to their normalpositions, the weighted dog G being operated by the plunger-head I onits return to open said dog. The Weighted end II ot` this dog closes thedog automatically and holds the plunger ready to be again projected.

X is a U-shaped bail hinged to the dog G, and provided with a hingedarm, Y, having the loop Z, which the knot Z strikes to release the dog.

Having described the invention, what I claim, and desire to secure byLetters Patent, 1s-

1. The combination, with the tube, and the casting having the recesswith pulley therein, of the plunger-rods with plunger-heads, theair-tight valve-head secured to the rear ends of the plungerrods, thespiral spring with valve-head B2 at its rear end, the drawrope with knotthereon, the weighted dog, and the bail with hinged loops, substantiallyas specified.

2. The combination, with the tube and casting, of the plunger-rods withthe air -tight valve-head at their rear ends,the spiral spring withvalve-head B2, the weighted dog with loop attached, and the knotteddrawrope, substantially as specified.

In testimony whereof I afx my signature in presence of two witnesses.
